Comment: Motixafortide (BL8040) is a CXCR4 antagonist that is being developed by Biokine Therapeutics [1]. It is a 14-residue polypeptide modified from a naturally occurring horseshoe crab protein. Motixafortide acts as an inverse agonist in [35S]GTPγS binding assays [1]. It induces safe and efficient stem cell mobilisation in MM patients in preparation for autologous stem cell transplantation [3], and it is being proposed as a mechanism to improve anti-tumour immune reponse against solid tumours [2].

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

Summary of Clinical Use Click here for help
Motixafortide (BKT140, BL-8040) was investigated for several indications including treatment of solid tumours (in combination with checkpoint inhibition by pembrolizumab), mobilisation of hematopoietic stem cells for autologous and allogeneic transplantations and hematological malignancies. In September 2023 motixafortide was approved by the FDA for use alongside filgrastim (G-CSF) as a stem cell mobilising agent to prepare for autologous transplantation in patients with multiple myeloma.
